The conventional way to find the coefficients of the second order equation is to solve the nonhomogeneous linear equation (Ax = b), where A is the Vandermonde matrix. Although this method seems to be quite simple to execute, matrix inversion must be performed at every iteration. Another disadvantage is that the Vandermonde matrix must be square, which means all data from the members in population cannot be used. Therefore, in this study, the iterative Kaczmarz's Method is integrated to IPSO. The obtained results are compared with the conventional algorithm.","PeriodicalId":108357,"journal":{"name":"2013 8th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117023785","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current feedback methods from both line and converter sides are compared and theoretical analysis is stated. The analysis is based on the existence of a critical resonant frequency dividing the controlling frequency interval into two regions; namely low and high resonant frequency regions. The feedback types and damping methods are evaluated for both low and high resonant frequency regions with regard to resonant and low frequency poles of the system. In the low resonant frequency region, damping of LCL-filter resonance is necessary for line current feedback; while the current controller provides inherent damping when converter current feedback is utilized. Moreover, total harmonic distortion (THD) and power factor performance of the designed system employing either line or converter current feedback is assessed under varying load conditions. Besides, thorough theoretical approaches supported with simulation results are presented.","PeriodicalId":108357,"journal":{"name":"2013 8th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125489622","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Detection is possible by exploring similar regions in an image and based on regional features' similarity. Many feature extraction algorithms are used to extract information from non overlapping blocks of the image. Similar features from separate regions are an indication of a copy move forged image. Image moments are used to represent the image blocks during forgery detection recently. Krawtchouk moments are used to extract regional features and detect copy move forgery in this paper. They are not used to extract features and detect forged images before. Experimental results indicate that the proposed method can detect copy move forgery for both regular and irregular shaped regions. Besides, the method is resilient to additive white Gaussian noise, blurring attacks. Experimental results also show that the method has higher accuracy ratio compared to similar works for post processed (Gaussian blurred) forged images.","PeriodicalId":108357,"journal":{"name":"2013 8th International Conference on Electrical and Electronics Engineering (ELECO)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127864210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A multi objective function is formulated to solve the optimization problem with considering multi carrier energy network operation costs, loss and voltage profile. Simulation carries out a 33 bus radial distribution network which is supplied with CHP in some buses. CPLEX solver of GAMS and Genetic Algorithm of MATLAB is employed to solve the problem.
